What is Triangle Solitaire?

Triangle Solitaire is a Pyramid variant with one key difference: the layout is an inverted triangle rather than a standard upright pyramid. Pairing still works exactly like Pyramid — ranks sum to 13 and Kings are removed alone. In a standard Pyramid, the apex is one card at the top with the base row of seven at the bottom. Triangle inverts this — the widest row is at the top and the layout narrows to one card at the bottom. This changes which cards are initially exposed and which are blocked.

Winning the triangle

Clear every card out of the inverted triangle to win. The single card at the bottom stays covered until both cards above it are gone, but other triangle cards may remain after it is removed. Unlike standard Pyramid, stock and waste cards do not need to be cleared.

How the inverted layout changes access

In standard Pyramid, the apex card needs its two covering cards removed. In Triangle, the bottom card likewise needs its two upper covering cards removed, but the top row is immediately and fully exposed. This means the opening is information-rich: many cards are available immediately, but they all share blocking relationships with the narrowing rows below.

The opening has seven exposed triangle cards. Compare pairs by whether they remove the second coverer of a card in the next row.

How Triangle compares

  • Pyramid — pairs totaling 13; upright layout; King removed alone
  • Relaxed Pyramid — same pairing rule, only pyramid needs clearing
  • Apophis — pairs totaling 13; three waste lanes
  • Giza — one pyramid and eight visible reserve piles
  • Tut’s Tomb — draw-three into one waste pile

Triangle is part of Pyramid Park · Pyramid & peaks and is a variant of Pyramid.
